SAW-JOINTEB.

SPECIFICATION forming part of Letters Patent No. 304,631, datedSeptember 2, 1884.

Application tiled March 5, 18811 (No model.)

to be afull, clear, and exact description thereof.

My invention relates to a new and useful machine which I call asawjointer, the object of which is to put in line the cuttingedges ofthe wedge-shaped point-s of the teeth' of a saw to make it run true; andit consists in a frame having an adjustable clamping de vice forsecuring the file and adjustable plates or bars for receiving andguiding the saw over the iile, as I shall hereinafter fully explain.

Referring to the accompanying drawings, Figure l is a perspective viewof my sawj ointer. Fig. 2 is an elevation, thelower portion of the twonearest standards being cut away, showing the jaws C and sliding piece Dbetween two of the standards in transverse section, and thecorresponding jaws (C) and sliding piece l) between the other standardsin elevation. Fig. 3- is an end elevation and part section.

A is abase-plate, provided with corner holes, a, whereby it may bescrewed to a block or table, or to a vise.

B are four uprights or standards,secured to the plate A by having theirends formed into bolts and passing through the plate, taking nuts below,by means of which they may be tightened down. Between each pair of thesestandards at the ends are the clamping devices for the iile. rlheseconsist ofthe spaced plates G,lying on each side of the standards andhaving the cross-jaws c inside of and bearing against the standards onone side, and the pieces D, sliding between the plates C, and having thejaws d, against which the screws d impinge, whereby said jaws may beadjusted toward jaws c.

Eare four guide plates or bars between and parallel with the standards.These are in pairs, and are supported by the thumbscrews F through thestandards, and by which they are also adjusted to or from cach other andto or from the standards.

G is the tile. This is laid flat on t-he clamps and is secured betweenthe jaws by tightening 5o up 'the screws d.

The saw is4 to be placed between the upright guide plates or bars E,with its-teeth resting upon the file, and the bars may then be adjustedto guide the saw blade or plate accurately as it is reciprocated overthe file, whereby the cuttingedges of its teeth are iiled down intoline.

In this device any size of ile may be used, and by proper adjustment ofthe guide-bars E the saw may be movedto operate over any protion of thefile'. For some saws (circular saws, for example) a short tile might beused. To provide for this, I have the series of holes a nearer together.The standards may be setup and secured in these, and as short a rile asnecessary used.

4VHaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-u 1. In a machine for lining thecutting-edges of the teeth of saws, a horizontal lile and the jaws c andd, for clamping or securing it lirmly, in combination with guides Eabove the le, in which the saw blade or plate is directed whilel 7 5 itsteeth are reciprocated over the file, substantially as described.

2. In a machine for lining the cuttingedges of the teeth of saws, ahorizontal iile and jaws c and d, for clamping it Irmly, in conibinationwith spaced guides above the le, for receiving and directing the saw,and thumbscrews for adjusting said guides toward or from each other andsidewise, to confine the saw-blade and move it, when desirable, over afresh portion of the iile, substantially as described.

3. In a machine for lining the cutting-edges of the teeth or' saws, thestandards B, the iile G between them, and jaws c and d, for clamping it,in combination with the guide-bars E between the standards, and theirsupporting and adjusting screws F, substantially as herein described.

4. In a machine l'or lining the eutting-edges of the teeth of saws, thebase-plate A, standards B, guide-bars E, and supporting and adjlisting-screws F, in combination with the iile G and the means forclamping it, consisting of for adjusting7 said bars, substantially ashereA the spaced plates G, having jaws c, the sliding in described.pieces D, having jaws el, and the adjusting- In witness whereof I havehereunto set my screws d, all arranged and operating snbstanhand. 5tially as herein described. his
